Celebrate System Administrator Appreciation Day

The 18th Annual System Administrator Appreciation Day is Friday, July 28, 2017.

As we pay tribute to the heroic men and women who keep your computer workstation working and your network running, take a few minutes to understand the role of a system administrator

The many tasks of the sysadmin

A system administrator, or sysadmin, manages a computer network.  At Guru42 universe we reflect upon the System Administrator and the Power User to illustate how a  sysadmin thinks in terms of managing systems rather than individual computers

The sysadmin maintains various generations of desktop computer hardware and workstation operating systems. They support various desktop installed software, as well as internet based computer applications. They're expected to know what applications work well with which web browser, and what plugins are needed for every website.

They may also be responsible for the local servers and network operating systems as well. Their many network duties could include monitoring internet security, and making sure the wireless network is functioning.

Depending on the size of the network the sysadmin may setup and maintain various user names and logins. They make sure end users are using proper procedures of accessing the network, and they are not wasting network resources watching silly videos not related to work.

Fighting the stereotypes

System administrators are often under management pressure to contain costs and are limited in terms of time and resources.

In their effort  to manage the computer network efficiently, the sysadmin is often stereotyped as a bitter control freak with the goal of standing in the way of end users.

Sysadmins oversee the installation of services and and software on the network purchased by non technical end users and managers, and take the blame for everything that goes wrong

When the sysadmin complaints  of network misuse or abuse, unrealistic end user expectations, and self inflicted problems, they are perceived as angry.

Why choose to be a sysadmin

You might wonder why someone would want a thankless job that is often associated with negative stereotypes.

Like many professionals who see their career as more than showing up to receive a paycheck, a good sysadmin  spends much of his spare time learning and sharing ideas and information with his colleagues because he enjoys the daily challenges of problem solving.

A good sysadmin thrives on the fact that the world of technology is always changing and never boring. 

Happy SysAdmin Day!

There is a holiday for everything else, so why not Sysadmin day?

Send out an email to the person who keeps your technology running smoothly, without having a computer problem to report, and simply say, Happy SysAdmin Day!

Debunking the Nikola Tesla myths by way of defending Thomas Edison

When I created the GeekHistory website my main goal was to draw attention to the many scientists and inventors that I call the forgotten geeks. It was not my plan to spend a lot of time defending Thomas Edison, after all he does get mentioned often.

As I revved up my writing for the GeekHistory over the last few years I have become active in social media looking for common questions about famous inventors and inventions. In search of information on all the "who invented it" myths of technology history I found a great deal of misinformation giving credit to Nikola Tesla for a variety of inventions. I find myself often defending Thomas Edison because of often over the top claims of everything that Nikola Tesla allegedly invented.

Nikola Tesla has a cult following that gives him credit for inventing just about everything. There are people who object to the phrase "the Cult of Tesla," but the Tesla fanatics are a prime example of a cult. Tesla fanatics have an "us against them" mentality with stories full of conspiracy theories of how the government took all of Tesla's files when he died. When it comes to any attempts to have a rational conversation, they deny any facts that might contradict the group's beliefs. Having a meaningful conversation with Tesla fanatics can be frustrating because there is a complete avoidance of critical thinking.

Studying the claims of Tesla fans, searching for the truth, has made me even more passionate about my original goals of drawing attention to the forgotten geeks who deserve to be remembered. One of the many claims of Tesla fans is that Tesla invented radio. In the process of digging deeper to learn more I came to appreciate the work of Fessenden. Who is the inventor who started his career working for Thomas Edison, later worked with George Westinghouse, and has a legitimate claim to be called the father of radio? The answer to that question is not Nikola Tesla, it is Reginald Fessenden.

From his work for George Westinghouse and the University of Pittsburgh, to the story of Fessenden's 1905 Christmas broadcast to ships at sea, he is indeed a forgotten geek that deserves to be remembered. Check out the complete story of Reginald Fessenden Canadian inventor of radio and wireless telephone

For all his quirks, I do appreciate the contributions of Thomas Edison. Including the mountains of material I have read, I have made two visits to the Henry Ford Museum of American Innovation and Greenfield Village near Dearborn, Michigan in recent years to study the accomplishments of Edison and other geeks. Just as I note the exaggerations of the Tesla fans, you can say that the claim that science becomes religion goes both ways. Henry Ford idolized Thomas Edison, you can clearly see that in the Henry Ford museum complex. The complete Menlo Park lab from New Jersey was transported to Michigan and rebuilt there. Henry Ford had a dedication ceremony for the reconstructed lab that Edison attended when it opened.

There are many forgotten geeks who made incredibly important contributions in bringing electricity to our homes. Nikola Tesla did not invent AC power generation. Tesla's sole contribution was his version of the polyphase AC motor. Significant, but it was theoretically described by other others before him, as were many of the other inventions and discoveries often credited to Tesla.

As we created the section on the history of electricity we broke it down into four sections starting with a list of scientists and inventors that contributed to our modern understanding of electricity.

Our next page looks at the European inventors before Edison and Tesla who contributed to the development of electricity and AC power distribution

It bothers me that so many internet sites talk about the War of Currents as the great battle between Edison and Tesla. Edison eventually lost control of Edison Electric as it merged with another company to become General Electric. Nikola Tesla was not a member of team Westinghouse when the War of Currents started between George Westinghouse and Thomas Edison. Follow this link to learn about the many Westinghouse Electric engineers responsible for electricity and AC power in our homes

Edison does deserve credit for many inventions in a wide variety of areas, and in defending Edison, I have come up with a fair amount of material for the GeekHistory websites. Edison might have been too stubborn to back down on DC power generation as the way to produce electricity, but he does deserve to be respected for launching the modern electric utility industry with the creation of the Pearl Street station in lower Manhattan in 1882 When the War of Currents ended around 1893, Thomas Edison was no longer in control of Edison Electric. But the Edison team (which became part of the General Electric Company) lived on in many ways.

Reginald Fessenden worked several years for Edison, before joining forces with Westinghouse. In the biography "Fessenden – Builder of Tomorrow" - by Helen Fessenden (his wife), you will find remarks by Reginald Fessenden defending the legacy Thomas Edison.

"The question has often been put to me 'Is Edison really a good inventor? Are not his inventions really due to his assistants?' Having worked with him for a number of years and having made a rather special study of the science of invention and of inventors, my own conclusion is that all of the inventions which go by his name were made by him personally, and that there is only one figure in history which stands in the same rank with him as an inventor, i.e. Archimedes."

Edison had the reputation of a hard driving businessman, but he was also passionate about creating an invention factory. Edison paid workers to conduct numerous tedious experiments so he did not have to do the boring manual tasks himself. I think that is pretty genius.

Some of the Tesla fans point to crazy things that Edison did to discredit him as an inventor. Don't get me wrong, Thomas Edison was no saint, he was a lunatic at times, but to discredit Edison as a means to glorify Tesla is more than a little humorous. Nikola Tesla cornered the market on craziness during his lifetime.

Wondering about the dark web and the forbidden fruit of the internet

The phrase forbidden fruit typically refers to engaging in an act of pleasure that is considered illegal or immoral. That fits the mold of many questions I am often asked, such as what are some of the illegal or immoral websites you can find on the mysterious and mythical part of the internet known as the dark web.  The mysterious dark web, sometimes called the dark net, is the fuel for spy movies. it helped to create WikiLeaks run by the super spy Julian Assange and it allows cyber snitches like Edward Snowden share secret information. People are axious to know how to find what is hinding beneath the surface in the dark web.

According to remarks made by Roger Dingledine at a recently Philly tech conference, the overall perception of the dark web is more mythical than factual.  Roger Dingledine is an MIT-trained American computer scientist known for having co-founded the Tor Project, aka "the dark web."  Dingledine spoke at the Philly Tech Week 2017 putting some of the myths and legends of "the dark web" into perspective.

The worldwide network known as “the dark web” uses specially configured servers designed to work with custom configured web browsers with the purpose of hiding your identity. You will see the term Tor servers and web browsers to describe this private network. Tor originally stood for "The Onion Router."  The Tor Project, Inc is a Massachusetts-based research-education nonprofit organization founded by computer scientists Roger Dingledine, Nick Mathewson and five others. The Tor Project is primarily responsible for maintaining software for the Tor anonymity network.

If you are looking for all that forbidden fruit hiding beneath the surface, according to Dingledine no more than one to three percent of the Tor Network’s traffic comes from “hidden services” or “onion services”, services that use the public internet but require special software to access. Dingledine claimed that onion services basically do not exist. He added that it’s a nonsense that there are “99 other internets” users can’t access.

One popular way often used to describe the deep web and dark net is to use a graphic of an iceberg. Dingledine advises his audience not to pay attention when someone uses the iceberg metaphor, and criticized the news providers who use the “iceberg metaphor” for describing the darknet and the deep web.  According to Dingledine, just about any use of the “dark web” phrase is really just a marketing ploy by cybersecurity firms and other opportunists.  So the forbidden fruit you were hoping to find really is just a myth after all.
